No, died again, but after I managed to move some purchases into Calibre - but as soon as I bought another, down it went.
So I'm gonna try de=registering and re-registering, see if that helps.
It's seems to me obviously something from Kindle that's doing this, but what I don't know.
And Registry cleaning, not that I know what that is, sounds fairly tricky, to Mr TechDunce here, but I'd have a go. I'll Google it !
And, Gecko, thanks, but that is what I do too, but the problem is that because K4PC isn't opening, it's not (presumably) recieving any new purchases, so when I hit "Add", there are no additions there that have been passed on.
When I un/reinstall they mysteriously drift across and there they are - then K4PC seems to get tired and relapse !
But will attack it later today .....
Mumble, mumble. mumble .....................
